Differential diagnosis of acute and subacute transverse myelopathy includes inflammatory, infectious, vascular, metabolic and paraneoplastic etiologies. Information on the diagnostic approach to transverse myelopathy with regard to daily clinical practice is provided. The differentiation between five lesion patterns on magnetic resonance imaging (MRI) in myelitis may be helpful: (1) longitudinal extensive transverse myelitis, (2) short segment ovoid or peripherally located, (3) "polio-like", (4) granulomatous and (5) segmental with rash...

Multiple sclerosis (MS) is a chronic inflammatory and demyelinating disease of autoimmune originate. The main agents responsible for the MS development include exogenous, environmental, and genetic factors. MS is characterized by multifocal and temporally scattered central nervous system (CNS) damage which lead to the axonal damage. Among clinical courses of MS it can be distinguish relapsing-remitting multiple sclerosis (RRMS), secondary progressive multiple sclerosis (SPSM), primary progressive multiple sclerosis (PPMS), and progressive-relapsing multiple sclerosis (RPMS)...

BACKGROUND: Co-occurrence of multiple sclerosis (MS) and glial tumours (GT) is uncommon although occasionally reported in medical literature. Interpreting the overlapping radiologic and clinical characteristics of glial tumours, MS lesions, and progressive multifocal leukoencephalopathy (PML) can be a significant diagnostic challenge. CASE PRESENTATION: We report a case of anaplastic astrocytoma mimicking PML in a 27-year-old patient with a 15-year history of MS...

Multiple sclerosis (MS) is a disabling disease, with the first symptoms mostly appearing early in life. In addition to the clinical and laboratory findings, imaging has become increasingly important for diagnosis, prognosis, and monitoring. Because of its importance for these purposes, a high level of knowledge of imaging MS pathology and a standardization of the imaging acquisition, interpretation, and reporting is necessary. Here we will describe the MR imaging characteristics of MS pathology, the current imaging protocols, diagnostic criteria, and the differential diagnosis of MS...

BACKGROUND: It has long been known that the majority of patients with multiple sclerosis (MS) display an intrathecal, polyspecific humoral immune response to a broad panel of neurotropic viruses. This response has measles virus, rubella virus and varicella zoster virus as its most frequent constituents and is thus referred to as the MRZ reaction (MRZR). OBJECTIVE: Re-evaluation of the specificity of MRZR as a marker of MS. METHODS: Structured review of the existing English-, German- and Spanish-language literature on MRZR testing, with evaluation of MRZR in a cohort of 43 unselected patients with MS and other neurological diseases as a proof of principle...

Intrathecal B-lymphocyte activation is a hallmark of multiple sclerosis (MS), a multi-factorial inflammatory-demyelinating disease of the central nervous system. Such activation has a counterpart in the cerebrospinal fluid (CSF) oligoclonal IgG bands (OCB), whose diagnostic role in MS has been downgraded within the current McDonald's criteria. With a theoretico-practical approach, the authors review the physiopathological basis of the CSF dynamics, and the state-of-the-art of routine CSF analysis and CSF biomarkers in MS...

BACKGROUND: The soluble isoform of the interferon-β (IFN-β) receptor (sIFNAR2) could modulate the activity of both endogenous and systemically administered IFN-β. Previously, we described lower serum sIFNAR2 levels in untreated multiple sclerosis (MS) than in healthy controls (HCs). OBJECTIVE: To assess sIFNAR2 levels in a new cohort of MS patients and HCs, as well as in patients with clinically isolated syndrome (CIS) and with other inflammatory neurological disorders (OIND) and to assess its ability as a diagnostic biomarker...

The analysis of intrathecal IgG, IgA and IgM synthesis in cerebrospinal fluid (CSF) and evaluation in combined quotient diagrams provides disease-related patterns. The compilation with complementary parameters (barrier function, i.e., CSF flow rate, cytology, lactate, antibodies) in a cumulative CSF data report allows a knowledge-based interpretation and provides analytical and medical plausibility for the quality assessment in CSF laboratories. The diagnostic relevance is described for neurological and psychiatric diseases, for which CSF analysis can't be replaced by other diagnostic methods without loss of information...

Multiple sclerosis (MS) is a demyelinating disease of the central nervous system of probable autoimmune origin. In this review of literature, the authors present a constantly broadening list of potential antigens, including myelin and non-myelin structures, that cause the autoimmune reaction. Determination of antibodies to any antigen has not sufficient specificity and sensitivity for the use in routine laboratory practice. Oligoclonal immunoglobulins determined with isoelectric focusing (IEF) technique are currently considered as the main immunological MS markers...

INTRODUCTION: Tumor necrosis factor-α (TNF-α) blocking agents may be associated with neurological adverse events, including demyelinating syndromes, that can be difficult to differentiate from multiple sclerosis (MS) and clinically isolated syndrome (CIS) as neither the clinical nor laboratory distinctive features have been reported. Usually clinicians mainly examine the diagnostic value of immunoglobulin G oligoclonal bands underestimating the value of other cerebrospinal fluid (CSF) parameters (such as CSF cytology)...

OBJECTIVES: Behçet's disease (BD) is a systemic auto-inflammatory disorder of unknown cause, which may affect the central nervous system in around 5% of the patients [neuro-BD (NBD)], usually causing large lesions encompassing brainstem, diencephalon and basal ganglia regions. Occasionally NBD patients present with white matter lesions necessitating differential diagnosis from multiple sclerosis (MS). In this study, the efficacy of Barkhof criteria was tested in diagnostic differentiation of NBD and MS...

Multiple sclerosis is a chronic demyelinating disease of the central nervous system that occurs primarily in young adults. There is no single diagnostic test to recognize the disease. The diagnostic criteria, based on clinical examination and laboratory tests, have changed considerably over time. The first guidelines involved only the results of the patient's neurological examination. The diagnostic criteria developed by Poser in 1983 were based largely on the results of additional tests, including visual evoked potentials and analysis of cerebrospinal fluid...

The immune system plays a major pathological and regulatory role in multiple sclerosis (MS) and, therefore, is a focus of extensive research. Animal models of MS have been crucial in understanding the pathological processes in MS and developing certain treatments, however, all crucial aspects of the human disease may not be appropriately modeled. With the exception of detecting oligoclonal bands and IgG synthesis in cerebrospinal fluids of MS patients, there has not been major progress in the development of immunologic tests that can be used for diagnosis of MS...
